Iyo COFDM isina waya yekufambisa systemine tarisiro yakafara yekushandiswa muzvikamu zvakawanda, kunyanya mumashandisirwo anoshanda mukufambisa kwakangwara, kurapa kwakangwara, maguta akangwara, uye mamwe minda, uko kunoratidza zvizere kushanda kwayo, kugadzikana, uye kuvimbika.
Zvakanakira zvakadai sekushandiswa kwepamusoro-soro, simba rinopesana ne-multipath interference capability, high-speed data transmission uye kuchengetedzwa kwepamusoro kunoita COFDM wireless transmission systems ive nehukuru hwekusimudzira.
Nekukurumidza kukura kwesainzi uye tekinoroji,wireless communication technologyrave richishandiswa zvakanyanya munzvimbo dzakasiyana-siyana.Pakati pavo, iyo COFDM (Coded Orthogonal Frequency Division Multiplexing) isina waya yekufambisa sisitimu yave zvishoma nezvishoma kuva nyeredzi tekinoroji mumunda wekufambiswa kwewaya nekuda kwekushandisa kwayo kwakanaka kwemavara uye kugona kwakanaka kwekurwisa-multipath kukanganisa.
Ichi chinyorwa chichaongorora zvakadzama misimboti, mamiriro ekushandisa uye zvakanakira COFDM isina waya yekufambisa masisitimu kana ichienzaniswa nemamwe matekinoroji.
1. Nheyo yeCOFDM isina waya yekutumira system
Iyo COFDM isina waya yekufambisa sisitimu inoshandisa chiteshi coding, chiratidzo modulation uye data transmission tekinoroji kuona kutapurirana kwemufananidzo data.Chekutanga, chiteshi coding inomanikidza uye inoisa iyo data data kudzikisa huwandu hwe data inofambiswa.Zvadaro, chiratidzo chemodulation chinogadzirisa iyo encoded data pane inotakura mune yakatarwa frequency bhendi kuti ione spectrum kuchinja kweiyo data.Iyo modulated siginecha inotumirwa kumagumo ekugamuchira kuburikidza nekutumira data kuti ipedze iyo isina waya yekufambisa yemifananidzo data.
2. Mamiriro ekushandisa eCOFDM isina waya yekufambisa system
2.1.Kufambisa kwakangwara
Mundima yehungwaru yekufambisa, COFDM isina waya yekufambisa masisitimu inogona kushandiswa mukutarisisa traffic, kuteedzera mota, kudzora chiratidzo chetraffic, nezvimwe kuvandudza kushanda kwe traffic uye kuve nechokwadi chekuchengetedza traffic.
Semuenzaniso, 100 bits yedata inoda kugadziridzwanokutitransmitting.Kutanga shandura iyo ku200 bits,.Kana chiratidzo chikagamuchirwa, kunyangwe paine dambudziko nekufambiswa kwe100 bits, iyo data chaiyo inogona kuramba ichideredzwa.Muchidimbu, ndeye kuwedzera redundancy pamberi pemodulation kuvandudza kuvimbika kwekutapurirana.Izvi zvinodaidzwa kuti Internal Error Correction (FEC) muCOFDM masisitimu.Uye it yakakosha parameter yeCOFDM system.
2.2.Smart kurapwa
Mumunda wekurapa kwakangwara, iyo COFDM isina waya yekutumira sisitimu inogona kuona mabasa akadai se telemedicine, isina waya yekuvhiya nhepfenyuro mhenyu, uye chaiyo-nguva kutapurirana kwemifananidzo yekurapa, kuvandudza kugona uye kunaka kwemabasa ekurapa.
2.3.Smart city
Mumunda weguta rakangwara, COFDM isina waya yekufambisa system inogona kushandiswa mukuchengetedzeka kwemadhorobha, kutarisa kwezvakatipoteredza, mwenje wakangwara, nezvimwe kusimudzira hungwaru hwekutonga kwemaguta uye kuvandudza hupenyu hwevagari.
3.Zvakanakira zveCOFDM isina waya yekufambisa system
Kuenzaniswa nemamwe mawaya ekukurukurirana matekinoroji, COFDM isina waya yekufambisa system ine zvinotevera zvakanakira:
1. High spectrum kushandiswa
COFDM tekinoroji inogona kushandisa zvizere bandwidth zviwanikwa uye kugadzirisa spectrum kushandiswa nekuparadzira data pamusoro peakawanda subcarriers ekufambisa.
2. Kukwanisa kupindira kwakasimba kwe-anti-multipath
COFDM tekinoroji inoshandisa orthogonality pakati pe orthogonal subcarriers kunyatso kupatsanura masaini enzira dzakasiyana-siyana pamagumo ekugamuchira uye kuderedza kukanganiswa kwekuwanda kwenzira.
3. High-speed data transmission
Nekushandisa yakakwira-odha modulation tekinoroji uye inoshanda coding algorithms, iyo COFDM isina waya yekufambisa sisitimu inogona kuwana yakakwirira-kumhanya kufambisa data.
4. Kuchengetedzwa kwepamusoro
COFDM tekinoroji inoshandisa encryption algorithms encrypt uye kuendesa data, zvinobudirira kuchengetedza kuchengetedzeka kwe data inofambiswa.Iyo COFDM isina waya yekutumira sisitimu ine yakafara tarisiro yekushandisa muminda yakawanda, kunyanya mune inoshanda maapplication muhungwaru hwekufambisa, hungwaru hwekurapa, maguta akangwara uye mamwe minda, uko inonyatso ratidza kushanda kwayo, kugadzikana uye kuvimbika.Zvakanakira zvakadai sekushandiswa kwepamusoro-soro, simba rinopesana ne-multipath interference capability, high-speed data transmission uye kuchengetedzwa kwepamusoro kunoita COFDM wireless transmission systems ive nehukuru hwekusimudzira.
Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, tine chikonzero chekutenda kuti COFDM isina waya yekutumira sisitimu ichaita basa rinowedzera kukosha mune ramangwana rewireless kutaurirana ndima.
4. Mhedziso
Kubva pa COFDM tekinoroji,IWAVE Communicationsyakagadzira nhevedzano yemidziyo isina waya yekutumira, iyo inoshandiswawo zvakanyanya mundima idzi.Midziyo inogadzirwa nekambani yedu inonyanya kutarisaiyo wireless transmission yenguva refuyepamusoro-tsanangudzo vhidhiyo, kunyanya mukufambiswa kwewireless kwedrones, iyo inopa kurerukirwa kukuru kwemahombekombe ekudzivirira ekudzivirira, kununura njodzi yekukurumidzira, kufambisa kwakanaka, nezvimwe.
